Broken Circuits in Matroids-Dohmen’s Inductive Proof

Discussiones Mathematicae Graph Theory
Similarity:
Dohmen [4] gives a simple inductive proof of Whitney’s famous broken circuits theorem. We generalise his inductive proof to the case of matroids

Forbidden-minor characterization for the class of cographic element splitting matroids

Discussiones Mathematicae Graph Theory
Similarity:
In this paper, we prove that an element splitting operation by every pair of elements on a cographic matroid yields a cographic matroid if and only if it has no minor isomorphic to M(K₄).
